For those too stupid or ignorant to know otherwise, getting Goods In Transit cover does not mean you have courier insurance, contrary to what misleading info you may or may not have read elsewhere.
From a recruiting website that shall remain nameless
"Need Courier Insurance? Get automatic approval of your GIT policy by arranging a policy with our preferred insurers. Call for a quote right now"
Fine if you need Goods in transit, but it's suggesting (by not telling the reader otherwise) that getting GIT cover is all you need.
Get pulled over without proper courier insurance, or have an accident, and your insurance WILL be null and void
